TPH Board – the Temperature Pressure Humidity Sensor Board


Out of stock

The TPH-board is a new sensor board for measuring the Temperature, Pressure and the Humidity (TPH!). This board has the Sensirion SHT21 humidity sensor and the Bosch Sensortec BMP180 pressure sensor (both capable of measuring temperature). Note that the TPH-board is only 3.3 volt compatible, which makes it perfect to use with boards like the SODAQ Mbili and Seeeduino Stalker but not suitable for 5V Arduino boards . Both the SHT21 and the BMP180 are connected through the I2C/TWI with the easy Grove-header. Pull-up resistors are available on the TPH-board, but if undesired you can disconnect them through the cut-trace on the back.
The Bosch Sensortec BMP180 is a new high-precision barometric pressure sensor. The pressure range is 300 to 1100 hPa and has a high relative accuracy of +/-0.12hPa (+/-1m). This version is almost identical to the older BMP085 and can be used with the same arduino libraries.
The Sensirion SHT21 is a digital humidity sensor. The relative humidity (RH) operating range is from 0 to 100% RH and has a precision of 0.04% RH.
You can use the standard Bosch BMP Library and the Sensirion SHT Library, but a new SODAQ Arduino library for the TPH-board is coming soon!
